To give you an example, the following CDM is also a commodity, except that China is a developing country and a seller of this carbon fund, and the Environmental Energy Exchange is an institution that maximizes the benefits of these commodities in China.

CDM, abbreviated as clean development mechanism in English, is one of the three cross-border greenhouse gas emission reduction mechanisms stipulated in Kyoto Protocol. The method of CDM is that developed countries provide funds and technology to developing countries to help them implement projects to reduce greenhouse gas emissions. The implementation of CDM project can help Parties to realize their commitment to reduce greenhouse gas emissions at a lower cost, and at the same time, it can promote the implementation of sustainable development strategy in China by introducing advanced and applicable technologies. For example, if developing countries reduce or avoid greenhouse gas emissions, they can get subsidies by selling these gases to developed countries (so-called carbon fund transactions). Related energy projects include: wind farms, garbage hotspots, etc. These projects can be certified by the Clean Office of the National Development and Reform Commission and relevant departments of the United Nations, which can reduce the amount of carbon dioxide every year according to the situation of enterprises. Sell their carbon fund indicators (confirmed by the above certification bodies) to enterprises in other developed countries (because of the high cost of changing the current energy supply system in developed countries, countries with Kyoto Protocol emission reduction targets have to buy carbon funds to obtain emission targets.
